I contacted the guy earlier today to ask whether it was a neck or bridge pickup and his returns policy if it did not work, his reply was as follows:

To be honest I don't know if it's a neck or bridge pickup as I have know idea what it came out of. ( a total guess would be an Aria pro 11, so that would be bridge ) As far as returns go I'm afraid you would have to take your chance with this one. I have no way to test it. So if you buy it, its yours.

It's only a 45, and in that condition not worth it imo as it looks like it was once covered, see the solder blobs on the back? I've gotten much better pickups for half that price.though it could be good to complete a project back to stock?

It IS well thought of, I've had 5 different sets now and only really liked 1 set, although that could be down to the guitar's woods admittedly.Personally I just don't think they are a good allrounder.to be fair though every set has had plenty of power on hand....
